FAQs on Reproduction in Organisms NEET Questions
1. What is the necessity of Reproduction?
Reproduction is a biological process that is responsible for the production of new species or Organisms. It plays a vital role in the ongoing continuity of the Organisms further, resulting in a healthy and balanced ecosystem. Without the stage of Reproduction, life will only be coming to an end as there would be intermingling of species. Reproduction takes forward evolution as well through the variations which are visible from the Reproduction itself. two types of Reproduction are present, namely sexual Reproduction and asexual Reproduction. Reproduction is the only way via which individuals can be created in any form of being.
2. Define Asexual Reproduction.
In this type of Reproduction, there is a production of offspring which only revolves around the participation of a single parent, and not both of them. That single parent in asexual Reproduction will divide and reproduce itself to reproduce it further. Different types of asexual Reproduction are budding, fragmentation, binary fission, and vegetative propagation. Certain Organisms in which asexual Reproduction is generally seen are single-celled Organisms like bacteria, amoeba, yeast cells, hydras, etc. Some of the other plant cells which go through the same are potatoes, ginger, sugarcane, etc. Asexual Reproduction is equally importnat as Sexual one as the world can not rely on one for Reproduction and there is no need for second partner in Asexual Reproduction.
3. Define Sexual Reproduction.
There is free participation from the ends of both the parents of the opposite sex in sexual Reproduction, unlike asexual Reproduction. The information related to genes is carried forward by chromosomes in the nucleus part of cells known by the name of gametes, later which fuse to form a diploid zygote. All the reptiles, dogs, cattle, birds, in short, all the multicellular Organisms, undergo sexual Reproduction only. It is a process of events that includes stages such as pre-fertilization, fertilization, and post-fertilization. Some of the major advantages related to this type of Reproduction are identical offspring with respect to genetics, variations, and enhancement in evolutionary advancements.
4. Why is there no Reproduction through cell division in multicellular Organisms?
Cell division can not be considered as a type of Reproduction for multicellular Organisms. The main reason which falls behind it is that it only has the capacity to increase the total number of cells in the body of Organisms. Hence, it will only lead to the overall growth of the body and can not lend a hand to the process of Reproduction in the same. Because of the complexity which lies in multicellular Organisms, it becomes tough for a single cell to produce different tissues.
5. Fertilization is not a compulsory event for the production of fruit in certain plants. Why?
There is the presence of certain fruits which are developed fully from the ovaries and are unfertilized, such as pomegranate and grapes. The scientific term which is used for them is parthenocarpic fruits. The flowers of these plants are sprayed with a hormone-related to growth which takes forward the process of fruit production even without fertilization. But talking about ovules, they remain the same and do not change into seeds. Hence, it is not a mandatory event for these plants to go through fertilization to produce fruits by any means.
